Wing 261
C&I energy storage cabinet
A 125 kW / 261 kWh liquid-cooled energy storage cabinet with an integrated bidirectional converter for industrial and commercial sites.
Why Wing 261
An all-in-one AC cabinet that combines five liquid-cooled LFP battery packs (1P260S, 832 V nominal), a 125 kW bidirectional converter and built-in BMS and EMS. It switches seamlessly between grid-connected and off-grid operation and outputs 340-400 V three-phase (3L/N/PE) at 50 Hz. It suits industrial sites, commercial centers, residential complexes and solar canopy EV charging.
Liquid cooling
Liquid cooling keeps the cell-to-cell temperature difference at or below 3 °C, supporting cycle life, operating stability and high power density operation.
High power, wide voltage, high efficiency
125 kW rated and 137.5 kW maximum output, 670-949 V battery voltage range and 340-400 V AC output for a range of grids and loads. Maximum efficiency is 98.6% and system efficiency is 88%.
Grid compliance
Designed to Chinese grid connection standards for energy storage, including GB/T 34120 and GB/T 36775, and tested to the IEC 61000 series for electromagnetic compatibility.
Remote management
WLAN, app, Wi-Fi, 4G, LAN and Bluetooth connectivity for cloud monitoring, strategy optimization and fault warnings.
